"Sure enough......" Lu Shuangchuan completely understood this time, "The septic tank will produce ammonia, and after the ammonia enters the pond through the air port, it dissolves in the water, polluting the water quality and producing a chemical reaction." In the long run, these fish will naturally rise to the surface due to lack of oxygen. The weather is getting colder, and there is not much forage in autumn, which leads to poor nutrition and poor fish physique, which is easy to get sick, resulting in fish epidermal infection, and there will be a wave of fish turning white belly and dying! ”

The village party secretary patted his thigh and said angrily: "This is a few acres of land at the head of the village near the septic tank, and some people have taken advantage of it and used this drainage method." Unexpectedly, it was the harm to these fish! These are short-sighted! So, what now? ”

Lu Shuang said: "Since the problem has been found, it will be easy to solve!" Just change the water! ”

"Drain the water now?" The village party secretary frowned, this is not a simple matter! Now is not the time to dry up the pond, and it is easy to cause a lot of fish to die! Again, releasing the water can easily cause the fish to run away!

"Isn't there a canal on the left side of the pond? You only need to introduce it from above, release water from below, and put a few fine-mouth fish nets on the mouth of the water to ensure that the fish are not lost! Li Xiuyuan immediately suggested.

Lu Shuangchuan looked at him appreciatively, "Yes, the water in the fish pond does not need to be drained, half of the water is retained, so that the fish can adapt to the environment, otherwise, the fish pond is an ecological circle and will adjust itself." Then just fill in the small ditch next to it! ”

As soon as the village party secretary heard it, he immediately began to contact the captain of the production team and began to change the pond water.

Because Li Xiuyuan's advice was very useful, the village party secretary asked him to command people.

Suddenly, everyone began to dig small canals in a hurry.

Lu Shuangchuan took advantage of the fact that when no one was around, she went to the laboratory again, and this time she prepared a large number of Qingda injections, and threw them into the pond to reduce inflammation for the fish.

Technician Yang began to scoff at this, and also made an opinion, "Fish are very fragile, and they can easily die in a new environment. If you change most of the pond for more than half of the water, the fish will surely die! You believe her opinion, this is the basic knowledge of veterinarians! ”

But the village party secretary is now completely a dead horse and a live horse doctor, and he only intends to take Lu Shuang's opinion.

The day after changing the pond water, Lu Shuangchuan put in the Qingda injection, but there was still a fish belly facing up.

Lu Shuangchuan organized people to pick them all up, and those who could be saved were saved, and those who could not be saved were kept and distributed to the people in the village when the time came.

Seeing this, Technician Yang gloated: "I said earlier, you don't believe me!" When the time comes, the fish in this pond will die, look at how you pay the public grain, hum, young people, don't come out and hang around if you don't have the ability, don't listen to the old man, and suffer in front of you! Just like you, you still want to cure the fish, phew, you really think you are Hua Tuo alive, and you can cure the animal with a wave of your hand! Hehe! ”

Li Xiuyuan and the village party secretary were very disgusted by Technician Yang's hindsight, but several other families were very worried.

Lu Shuang turned a deaf ear, and still kept pace as always, not disturbed at all, only to increase the input of bait.

On the fifth day, Technician Yang was still taunting them.

And Li Xiuyuan, who was guarding the pond, came to report the good news: "Secretary, Ah Shuang, good news, good news, there are no dead fish in the fish pond today, not a single one!" ”

is always silent, his face is full of joy that is difficult to hide, and the corners of his eyes and eyebrows are full of joy.
